Rehabilitación estructural a un edificio sometido a asentamiento diferencial

Abstract

The present study analyzes the pathological behavior of the San Martín residential structure, located in Montería, Córdoba, which shows differential settlements compromising its verticality and overall performance. The building, over twenty years old and 54.44 meters high, consists of fourteen habitable levels and three technical levels. Its foundation combines a slab with 36 piles of 15 meters deep, in addition to a frontal sector supported by 8 piles of 25 meters, with the remaining area resting on a slab used for parking. After its construction was abandoned for approximately eight years due to the bankruptcy of the original company, the property was resumed by new owners and completed in 2014. Since its commissioning, the structure has presented increasing inclinations and settlements, possibly derived from deficiencies in the foundation process or undocumented changes during construction. The methodology included precision topographic measurements over several months to quantify settlements and deformations in columns, inspection visits to identify structural and non-structural damages, and a review of original design reports under NSR-98 regulations compared to current NSR-10 standards. The results revealed progressive differential settlements, affecting both structural stability and functionality. These findings highlight the importance of continuous monitoring, proper geotechnical evaluation, and compliance with updated regulations to guarantee safety and performance in high-rise buildings subject to pathological conditions.
